So, when I first got on the birth control, my dr said to take it immediately regardless that i was still going to have my period the next week. So i did, she said to use back up protection for the first 14 days and then after I'm good, but i've read that you only need back up protection for the first 7 days, and i've also heard it's not effective up until a month. It's been 19 days now and i'm still using back up protection, i havent missed a pill and i've taken it on time EVERY time, on the dot. I was just wondering if something were to happen, am I safe? I'm just a little worried here and there sometimes.
